Excited to share that our paper on modeling the Human Visual System with @meenakshik93 and Ishaan Chadha has been published under #CCN2025 (8-page paper track)! arxiv.org/pdf/2410.14031 (1/n)

MIT neuroscientists have identified parts of the brain’s visual cortex that respond preferentially when we look at “things” — that is, solid objects like a bouncing ball. Other brain regions are more activated when looking at “stuff” — liquids or granular substances such as sand.

🚨 Spotlight @ICML2025 🚨

Chi-Ning and Hang have been thinking deeply about how feature learning reshapes neural manifolds, and what that tells us about generalization and inductive bias in brains and machines. 

They put together the thread below, which I’m sharing on…

How is high-level visual cortex organized? In a new preprint with @martin_hebart & @KathaDobs, we show that category-selective areas encode a rich, multidimensional feature space 🌈 biorxiv.org/content/10.110… 🧵 1/n


A very well-written piece on how LLMs' successes can be attributed to learning from the shadows of human intelligence on Plato's cave

I always found it puzzling how language models learn so much from next-token prediction, while video models learn so little from next frame prediction. Maybe it's because LLMs are actually brain scanners in disguise. Idle musings in my new blog post: sergeylevine.substack.com/p/language-mod…

Why is backpropagation biologically implausible? And what might the brain do instead? 🧠 In the newest video we explore Predictive Coding – a biologically-inspired learning algorithm and derive it from scratch This was one of my favorite videos to make so far :)…

In a study now out in @eLife, @GeorginJacob @PramodRT9 and I have some exciting results: a novel computation that helps the brain solve disparate visual tasks, a novel brain region that performs this computation....what's not to like?! Read on.... 1/n elifesciences.org/articles/93033

We built an AI assistant that plays Minecraft with you. Start building a house—it figures out what you’re doing and jumps in to help. This assistant *wasn't* trained with RLHF. Instead, it's powered by *assistance games*, a better path forward for building AI assistants. 🧵
